滩海区唐南构造岩石物理研究及其意义

PETROPHYSICAL RESEARCH AND ITS SIGNIFICANCE IN TANGNAN STRUCTURE OF TANHAI AREA

依据歧口凹陷唐南构造中浅层地震地质条件,通过对岩石物性纵向变化特征、相互关系及地震属性参数卓有成效的分析和研究工作,提出并明确了该区地震响应特征及地震属性参数的地质含义,为有选择性地进行储层厚度、物性及含油性的预测奠定了坚实的基础,同时预测精度得到明显提高.依据其研究成果部署的2口预探井、4口开发井均获得显著钻探效果.

Detailed analyses of vertical lithological variations, their relationship, and seismic property parameters on the basis of shallow seismic conditions at Tangnan structure of Qikou depression reveal the geological conotations of acquired seismic responses and property parameters. A good foundation is thus available for a more reliable prediction of reservior thickness and property, and oil-bearing property. The allocated two pre-exploration wells and four exploitation wells have obtained good drilling effects.
